ABSTRACT:
The apparatus has an operating structure which is suspendable, by means of cables, from the barycentric hook of a helicopter and is provided with an orientatable arm having a cleaning head rigidly associated therewith. The cleaning head is provided with supports for suspending rotating cleaning brushes actuated by motors. Part of the suspension support is fixed and is constituted by a frame connected to the orientatable arm, and a movable support is supported by the frame so as to be oscillatable and is controlled by motors which allow to move the related brush or brushes from an open approach position to a closed operative position in which the set of brushes of the head embraces the set of insulators.
